Here she is. I told the seller that I am a big fan and I asked if he was on the crew. He seems like a very nice fellow. He sent me this reply:

Hello great to hear you love the show I was on the crew for 3 seasons, I was a set dresser whose job is to make the bar look like a real bar. And any new sets that would come in to make them look as real as you can because the show was shot on a sound stage. The jacket was a wrap gift at the end of a season the producers would buy the crew gifts. Enjoy it Johnny

I'd love to pick his brain but I don't want to bug him. In any case, the jacket rocks. Fits perfectly. This is my first purchase of anything so directly related to the show. The best part is, I can actually use it!
